The nature of bubble growth under different system pressures in a narrow channel

▶ We find that Sliding bubble growth occurs under higher system pressure (6-10 bar). ▶ The heat transfer situation is quite different under different system pressure. ▶ The latent heat needed for a bubble increases with increasing system pressure. ▶ So the bubble size and bubble growth rate decrease with increasing system pressure. ▶ Also a method for non-dimensionalizing the bubble radius and growth time is proposed.
